<p>Provided are a method and device for establishing a multi-protocol label switching traffic engineering tunnel. The method for establishing a tunnel includes: a second routing device receiving an identifier of an MPLS TE tunnel from a first VPN instance to a second VPN instance, which is sent by a first routing device; the second routing device, according to the identifier, acquiring path information about the MPLS TE tunnel from the first VPN instance to the second VPN instance, and establishing an MPLS TE tunnel from the second VPN instance to the first VPN instance based on the acquired path information, so that forward/reverse bidirectional tunnels share a common path or partially share a common path, thus solving the problem caused due to no common path when BFD is performed.</p> |
